2. De-energize the drive, isolate and lock out the control power, and
remove all wire connections from the unit. (View 1)
3. Remove quantity of (4) M6 (H.H.T.R.S.) that will allow the DC/DC
Power Supply Assembly to be removed from the Low Voltage Panel.
(View 1)
4. Remove quantity of (4) M4 (P.H.M.S.) and Nylon Shoulder
Washers from the back of the Mounting Plate. ( View 2)
5. Replace old DC/DC Power Supply with the new one.
NOTE: Make sure the Black Insulation is between the DC/DC
Power Supply and the Mounting Plate. Repeat Steps 4, 3, 2, 1
in this order to replace unit. (View 2)
6. Ensure the ground wire of P4 plug is connected to the ground by M10
bolt
